HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 521, 379, 255 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 521, 379, 255 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 521, 379, 255 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 521, 379, 255 is 1.

HCF(521, 379, 255) = 1

HCF of 521, 379, 255 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 521, 379, 255 is 1.

Highest Common Factor of 521,379,255 using Euclid's algorithm

Highest Common Factor of 521,379,255 is 1

Step 1: Since 521 > 379, we apply the division lemma to 521 and 379, to get

521 = 379 x 1 + 142

Step 2: Since the reminder 379 ≠ 0, we apply division lemma to 142 and 379, to get

379 = 142 x 2 + 95

Step 3: We consider the new divisor 142 and the new remainder 95, and apply the division lemma to get

142 = 95 x 1 + 47

We consider the new divisor 95 and the new remainder 47,and apply the division lemma to get

95 = 47 x 2 + 1

We consider the new divisor 47 and the new remainder 1,and apply the division lemma to get

47 = 1 x 47 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 521 and 379 is 1

Notice that 1 = HCF(47,1) = HCF(95,47) = HCF(142,95) = HCF(379,142) = HCF(521,379) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 255 > 1, we apply the division lemma to 255 and 1, to get

255 = 1 x 255 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 255 is 1

Notice that 1 = HCF(255,1) .
